Hexxagon probably isn't one of the first games you think of when it comes to retro classics, but it was such a great game that I had to remake it in Flash. It's an adaptation of the board game Ataxx by the now sadly defunct Argo Games in 1992. You play as the red diamonds and your opponent (either another player or the computer) plays as the blue globules. Your goal is to take over all the spaces on the board, and you do this by leaping into the spaces next to your opponent's pieces.
